/**
* This is an implementation of NTLM authentication that does single-signon
* by obtaining the user's Unix username, parsing it into DOMAIN\name format,
* and then asking Samba's ntlm_auth tool to do the authentication for us
* using the user's password cached in winbindd, if available. If the
* password is not available then this component fails to instantiate so
* nsHttpNTLMAuth will fall back to a different NTLM implementation.
* NOTE: at time of writing, this requires patches to be added to the stock
* Samba winbindd and ntlm_auth!
